These morons had the chance to release a book that could have changed the SNMP and network management environment forever. Instead, they decided to release the book with all examples built using the proprietary Tickleman extensions. Telling me as a reader that it is very easy to port to Scotty, just shows how harebrained they are. If I'm reading and deploying examples to understand and tweak for my own use, I don't want to understand the difference between two toolkits (especially, as if it is so easy, why didn't they use Scotty?).
Again, this could have been a great book, but I'm mostly regretting spending money on it as I never intend to finish it.
My recommendation is to burn it at the first chance and make rude noises to the authors that seem dislocated from reality (no wonder network people get anti-social stigma, when they have people like these among them).
